Slow fps on MF compared to HandBrake's last version

Post by orbot »

MAC PRO 2.66 1Gb tried most settings...

On MediaFork 0.8.0b1 build, MP4+MPEG-4 and FFmpeg or h.264 I'm lucky if I break 8FPS. CPU and MEMORY look normal. MEdiaFork CPU sample shows

2007-04-03 11:59:13.194 sample[8285] thread_read_stack: invalid frame pointer: 000003c0
2007-04-03 11:59:13.204 sample[8285] thread_read_stack: invalid frame pointer: fffffff1
2007-04-03 11:59:13.224 sample[8285] thread_read_stack: invalid frame pointer: 000002d0
2007-04-03 11:59:13.244 sample[8285] thread_read_stack: invalid frame pointer: 000002d0
2007-04-03 11:59:13.264 sample[8285] thread_read_stack: invalid frame pointer: 00000280
2007-04-03 11:59:13.275 sample[8285] thread_read_stack: frame pointer is zero, continuing.
2007-04-03 11:59:13.284 sample[8285] thread_read_stack: stack appears to be corrupt or in inconsistent state. Truncating stack.

Same DVD on HandBrake easily over 100FPS.

Am I missing something obvious?

100FPS ?!?!!? what resolution are you encoding to? i have the same machine as you and i consistently get 25FPS when encoding at 720x... @2400.

your numbers seem a little extreem on both ends of the spectrum, i can say when i get dropped audio my FPS goes down to about 8. Having said this, I do not believe your problem to be dropped audio right now.

Well, using ffmpeg it is quite easy to get 100+ fps, even with a debug build on a single-core athlon64, so it is not at all extreme that he is getting 100+ fps with ffmpeg. x264, however should be much slower than this, (around 25 or so seems right for my single-core) but 8 does seem a little low for either.

I don't have a Mac, so I'm not sure what more information the other devs that do will need, hopefully one of them will step in to help out.

Ok..I just re-read my post and 100FPS is not exactly right...at 640x480@1000 I'm getting never better than 7 or 8FPS. Same settings on handbreak and the same DVD rips in < 50min sorry I can't find where I jotted the exact FPS but it's what I would expect to get.

well..looking through other posts on "slow rips" etc... one caught my eye. The poster indicated that he had similar problems that were cleared up when he rebooted. A dev responded acknowledging the resolution but indicating his surprise since MAC's don't ususally require a reboot after app install.

Well...exhausting all other apparent options, I rebooted my MAC and low and behold...

Superman Returns using x264 witha res of 640x @2400 mow rips in a little over 1 hour at 45fps. I can live with that.

note: When it was problematic, I did notice lots of seek noise from my built-in drive...now nonelll
